Here are 3 SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your current
tree, that should be trivial to handle (one file modified by two things,
one file deleted.)
All 3 of these have been in linux-next for a while, with no reported
issues other than the merge conflict.

For platforms where multiple packages/die, this makes "Package-" key
duplicate. To make unique, add die and cpu id to key name.
So "Package-0" key name will change to "Package-0-die-x:cpu-x".
For example:
$sudo ./intel-speed-select -f json perf-profile info
Intel(R) Speed Select Technology
Executing on CPU model:106[0x6a]
{
"package-0:die-0:cpu-0": {
"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
...
...
"package-1:die-0:cpu-16": {
"perf-profile-level-0": {
"cpu-count": "32",
"enable-cpu-count": "32",
"enable-cpu-mask": "ffff0000,ffff0000",
...
...
For non json format, there is no change. Here when print_package_info()
is called, it will return the level to print for other information.
This level is used formatting. Also in some function duplicate code
was there to print package,die and CPU information. Replace all that
code with a call to print_package_info().

Treat a case when mailbox/mmio command can't be handled by the kernel
drivers when the module is removed or send a command which no driver can
handle. In this case ENOTTY result is returned, so print error.
Also when the isst_if_mmio module is removed, we can't send CLOS message
messages via Mailbox on non SKX based platforms. When this module is
removed, isst_platform_info.mmio_supported is set to 0. So it can't be
used as a condition to send via mailbox. Here replace check for Skylake

Once the CPU is offline, the topology information (core-id, package-id,
die-id) is not accessible via sysfs. So when user selects a config level
more than base config 0 and offlined CPUs to match the config level,
to return to base config he has to manually online CPUs before. Without
this CPUs information mapping from Punit CPU numbering will lot work
as it needs atlest package id for each CPU.
To avoid this additional steps store the topology information in a file
, which is created on the very first run after boot. Since system boots
in base config and all CPUs are online, we can get information about
every CPU.
Once any of the APIs like get_physical_package_id(),
get_physical_core_id() or get_physical_die_id() fails to read from
sysfs, read from the stored mapping file.
This mapping file is stored in /tmp file system. so on every boot
it is recreated to make sure that any new CPUs are added to the
system before boot are taken into account.
But don't use the stored physical device id when trying to get
information for CPU to send message in for_each_online_package_in_set().
Here use the real value from syfs and in case fails try the next CPU.

There are two instances of “speed-select-turbo-freq” underneath
“perf-profile-level-0” for each package. When we load the output into
python with json.load(), the second instance overwrites the first.
Result is that we can only access:
"speed-select-turbo-freq": {
"bucket-0": {
"high-priority-cores-count": "2",
"high-priority-max-frequency(MHz)": "3000",
"high-priority-max-avx2-frequency(MHz)": "2800",

When mailbox command for the turbo-freq enable fails, then don't display
result for auto-mode. When turbo-freq enable fails, there is no point
to set CPU priorities.

Prevent cpufreq from creating excessively large stack frames and fix
the handling of devices deleted during system-wide resume in the PM
core (Rafael Wysocki), revert a problematic commit affecting the
cpupower utility and correct its man page (Thomas Renninger,
Brahadambal Srinivasan), and improve the intel_pstate_tracer
utility (Doug Smythies).

Pull x86 cpu-features updates from Ingo Molnar:
"The biggest change in this cycle was a large series from Sean
Christopherson to clean up the handling of VMX features. This both
fixes bugs/inconsistencies and makes the code more coherent and
future-proof.
There are also two cleanups and a minor TSX syslog messages
enhancement"
